Autotransformer vs Isolation Transformer | Isolation .

The term "auto" refers to a single coil acting alone, not to any kind of automatic mechanism. In an autotransformer, portions of the same winding act as both the primary and secondary sides of the transformer. Operation of an Isolation Transformer. The primary purpose of an isolation transformer is to isolate circuits.

Isolation Transformer | Electrical4U

Transformers are electromagnetic devices which transform alternating current (AC) electrical energy from primary to secondary side. The energy is transformed with equal frequency and approximately equal power by means of the transformer core magnetic field. Thus they provide galvanic isolation in the electrical system. The isolation transformers .
